Given numbers are 263,680,989,845,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,680,989,845,663 is 89674489320.
Find LCM of 263,680,989,845,663 with Prime Factorization
| 5 | 263, 680, 989, 845, 663 |
| 13 | 263, 136, 989, 169, 663 |
| 17 | 263, 136, 989, 13, 51 |
| 263, 8, 989, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 17 x 263 x 8 x 989 x 13 x 3 = 89674489320
Therefore, the lowest common multiple of 263,680,989,845,663 is 89674489320.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
263 x 680 x 989 x 845 x 663 = 99090310698600
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
263 : 1, 263
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
989 : 1, 23, 43, 989
845 : 1, 5, 13, 65, 169, 845
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,680,989,845,663, is 1.
Now, the common factors can be found like this.
263:263
680:2x 2x 2x 5x 17
989:23x 43
845:5x 13x 13
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 17 = 1105
Therefore, the value for common factors is 1105.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 99090310698600/(1x1105)
LCM = 99090310698600/1105
LCM = 89674489320
Thus, we can understand that the LCM of 263,680,989,845,663 is 89674489320.
